COMPOSITION FOR EARTH-FILLED STRUCTURE AND EARTH-FILLED STRUCTURE BASE ERECTION IN CIVIL, INDUSTRIAL AND HYDRAULIC CONSTRUCTION INDUSTRIES

摘要

FIELD: building materials used in civil, industrial and hydraulic structure construction, particularly to erect ground embankments (in reclamation leveling, motor roads, dams and so on construction) and bases thereof.;SUBSTANCE: composition is based on ferric, aluminum and silicon oxide mixture. The mixture includes sandy mud deposits obtained during alumina production. Composition comprises (% by weight): ferric oxide - 30-75, aluminum oxide - 10-40 and silicon oxide - 0-5, additives (titanium, sodium, phosphor oxides and bound water) - 1-20. At least 80% of particles have dimensions of more than 0.1 mm.;EFFECT: possibility to use waste materials, increased ecological safety and decreased costs of structure erection.;1 ex
